What the FY2027 request buys
Verbatim from the R-2A exhibit for project 634869 of PE 1206310SF. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.
Tranche 0 - Conduct residual experimentation in support of PWSA risk reduction. - Conduct end-of-life fleet operations. Tranche 1 - Resolve anomalous behavior in system interoperability and compatibility, including optical communications, space-to-ground radio frequency (RF), Link 16, and Networking. - Continue mission engineering support activities including Concept of Operations (CONOPS) and Concept of Employment (CONEMP) development, user segment integration, developmental and operational test planning, and characterization and modeling of system performance targeting advanced use case capabilities. - Augment User Guides and Interface Control Documents (ICDs) and conduct integration and test activities to onboard additional Transport mission partners. Tranche 2 - Continue supporting risk reduction of Transport Layer Tranche 2 (TLT2) satellites, ground systems, and integration. - Continue mission engineering support activities including Concept of Operations (CONOPS) and Concept of Employment (CONEMP) development, user segment integration, developmental and operational test planning, and characterization and modeling of system performance. - Continue development of user Interface Control Documents (ICDs). - Fund mission unique hardware and integration of the T2 space vehicles on the National Security Space Launch (NSSL) Launch vehicles. - Complete payload and space vehicle manufacturing, assembly, integration and test activities. - Continue to support ground activities to ensure integration with PWSA Operations Centers. - Continue space vehicle FlatSat development and operations testing. - Complete Transport payload ground calibration and space vehicle environmental test campaigns. - Transition to nominal operations and conduct space vehicle command and control, and enterprise management, and sustainment for all TLT2 satellites. - Conduct system level verification and Developmental Testing. - Begin software updates and testing on-orbit defect discoveries made during on-orbit functional and performance testing. - Begin early Operational Testing of TLT2 capabilities. Tranche 3 - Continue Ground Entry Point (GEP) global footprint expansion in support of Tranche 3 (T3) launches. - Continue development of the PWSA Ground Segment and capability delivery in support of T3. - Continue PWSA ground segment evolution, enhancing PWSA framework capabilities for future Tranches. Risk Reduction Activities - Continue to conduct analysis, pursue tech maturation initiatives, and apply lessons learned to inform on-going and future development and delivery activities for data transport at the tactical edge. Tranche x Demonstration and Experimentation System (TxDES) - Demonstrate and advance the PWSA architecture and its components to fill existing and future gaps to support warfighting capabilities in Missile Warning, Missile Tracking and Missile Defense. The program provides rapid 2-year sprints supporting vendor development, technology maturation and risk reduction in both government-dedicated and commercial connected capabilities. Projects may include: • PWSA integration with pLEO Space Data Network (SDN) • Development of new sensor technology for Tranche 3+ • Acceleration of PWSA integration into Current Missions (BMC3 across the kill chain) • Development of enhanced tipping and queuing sensors for Combat ID • Deorbit as a Service for proliferated constellation maintenance • PNT over communication channels, PNT SA payload upgrades and light weight PNT signal demonstrations to support user integration prior to operations Advanced Fire Control (AFC) - Perform integration testing between Fire-control On Orbit-support-to-the-war (FOO) Fighter and the Demonstration Operations Center (DOC).Continue Advanced Fire Control Ground Infrastructure (AFCGI) effort to provide a common, enduring ground infrastructure and resources to minimize cost and complexity for fire-control-related space vehicle demonstration and experimentation programs (beginning with FOO Fighter). - Continue execution of other advanced fire control efforts including Warlock and Goliath. Other activities in this line may include, but are not limited to program office support, studies, technical analysis, experimentation, etc.
FY 2027 decreases from FY 2026 due to adjustments for other United States Space Force priorities.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Tranche 0 - Continue to conduct post-Capstone demonstrations and experimentations with warfighters. - Begin end-of-life operations on select satellites. Tranche 1 - Resolve anomalous behavior in system interoperability and compatibility, including optical communications, space-to-ground radio frequency (RF), Link 16, and Networking. - Continue mission engineering support activities including Concept of Operations (CONOPS) and Concept of Employment (CONEMP) development, user segment integration, developmental and operational test planning, and characterization and modeling of system performance targeting advanced use case capabilities. - Augment User Guides and Interface Control Documents (ICDs) and conduct integration and test activities to onboard additional Transport mission partners. Tranche 2 - Support risk reduction of Transport Layer Tranche 2 (TLT2) satellites, ground systems, and integration. - Continue interoperability and compatibility testing for key T2 interfaces including optical communications, space-to-ground radio frequency (RF), Link 16, tactical satellite communications (TACSATCOM), Integrated Broadcast Service - Low Earth Orbit (IBS-L), and Networking and Encryption. - Continue mission engineering support activities including Concept of Operations (CONOPS) and Concept of Employment (CONEMP) development, user segment integration, developmental and operational test planning, and characterization and modeling of system performance. - Continue development of user Interface Control Documents (ICDs). - Fund mission unique hardware and integration of the T2 space vehicles on the National Security Space Launch (NSSL) Launch vehicles. Tranche 3 - Expand Ground Entry Point (GEP) global footprint in preparation for launch of Tranche 3 (T3) space vehicles. - Continue development of the PWSA Ground Segment in support of T3. - Initiate PWSA ground segment evolution, enhancing PWSA framework capabilities for future Tranches.

Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 379.2 |
| FY2026 | Enacted | 453.0 |
| FY2027 | Request | 313.7 |
This activity is 100% of project 634869's FY2027 request and 100% of PE 1206310SF's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
